WS-C3750E-24TD-E is an enterprise stackable Layer 3 access switch with 24 Gigabit copper ports, two fixed X2-based 10 Gigabit Ethernet uplinks, and the IP Services feature set. The Rack-Mount 1U chassis belongs to the Cisco Catalyst 3750-E Series and provides data-only connectivity; powered endpoints need separate power arrangements. The discontinued WS-C3750E-24PD-E is the PoE sibling, so its endpoint-power role differs from this configuration. X2 uplink interfaces also distinguish this chassis from switches carrying built-in SFP+ cages, which matters when matching existing optical equipment. An out-of-band Ethernet management port and an RS-232 console port provide separate administrative connection points. Specify the complete part number when matching hardware to an existing installation rather than treating every 24-port model as interchangeable.

160 Gbps switching fabric capacity defines the hardware switching capability, while 65.5 Mpps forwarding specifies processing for 64-byte packets. OSPF, EIGRP, BGPv4 and IS-ISv4 support dynamic IPv4 routing; OSPFv3 and EIGRPv6 cover IPv6, and PIM-SM supports multicast routing. WS-C3750E-24TD-E carries 256 MB DRAM and 64 MB flash for runtime resources and software storage. Cisco Catalyst 3750E-24TD supports 11000 total unicast routes with the routing SDM template. The 12000-entry MAC maximum uses the VLAN template instead, so those maxima are not simultaneous allocations. 64 Gbps StackWise Plus throughput applies to the stack ring, while traffic between ports on the same member can switch locally without traversing that ring. RSTP and MSTP provide loop control, and cross-stack EtherChannel distributes a link bundle across members. Four egress queues per port separate traffic classes for scheduling. A second internal power supply cannot be installed.
New sealed and certified refurbished WS-C3750E-24TD-E units are offered with ORM warranties of up to 3-year extended coverage for new units and up to 1 year for certified refurbished units; 30-day returns apply to every condition, terms apply. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, and clean boot; firmware is verified and configuration wiped to factory default. Specify the condition and required accessories on the purchase order; Cisco's former 90-day limited hardware and software warranty has ended, and Cisco service ended January 31, 2018. Enterprise and volume orders have PO acceptance, Net-30 for government, and RMA with advance replacement, with regional stock and RMA across the UK, EU, US and MEA.

When an existing stack needs another member, cable reach and rack placement belong on the same purchase order as the chassis. CAB-STACK-50CM=, CAB-STACK-1M= and CAB-STACK-3M= provide different connection lengths. Record the installed member mix and select the required cable length before ordering the additional unit.
When an access refresh places gateway redundancy on the switch, the proposed configuration needs an interface-level review rather than a port-count check alone. HSRP supports 32 links per unit or stack. Specify the gateway links and peer configuration before approving the routed-access equipment list for the purchase order.
When the purchase supports a validation bench rather than a production replacement, frame-size requirements need to be included in the test plan. The Gigabit interfaces support 9216-byte jumbo frames. Specify the intended frame size and confirm connected equipment can use the same setting before releasing the staging purchase order.
Cisco-supported hardware for new deployments
WS-C3750E-24TD-E passed its last support date on January 31, 2018. C9300-24T-A is the current migration endpoint; the intervening WS-C3750X-24T-E and WS-C3850-24T-E models are discontinued.
PoE-powered phones or access points
WS-C3750E-24TD-E supplies no endpoint power through its copper ports. C9300-24P-A provides a current 24-port PoE+ alternative with Network Advantage rather than the legacy IP Services feature set.
Two internal redundant power supplies
WS-C3750E-24TD-E has one internal power-supply slot. Backup power uses external PWR2300-AC-RPS-N1=; a second internal supply cannot be installed in this chassis.

WS-C3750E-24TD-E identifies a Catalyst 3750-E switch with the IP Services feature set. WS-C3750E names the series, 24TD identifies the 24-port data configuration with two X2-based 10 Gigabit Ethernet uplinks, and the final E selects IP Services. The configuration includes a C3K-PWR-265WAC power supply.
WS-C3750E-24TD-E is managed through the Cisco IOS CLI over console, Telnet or SSH, browser-based device manager, Cisco Network Assistant, CiscoWorks LMS and SNMP. Administrators can use the dedicated Ethernet management port. SSH and SNMPv3 require a cryptographic software image, so confirm the installed image before selecting encrypted management access.
WS-C3750E-24TD-E reached end of sale on January 30, 2013, and its last date of support was January 31, 2018. Software maintenance ended January 30, 2014, and vulnerability support ended January 30, 2016. Cisco service has ended; purchasing a sealed unit does not restart those lifecycle milestones.
ORM offers WS-C3750E-24TD-E new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for certified refurbished units. Returns cover 30 days on every condition; terms apply. Cisco's original 90-day limited hardware and software warranty has ended; Cisco service ended January 31, 2018.
WS-C3750E-24TD-E includes IP Services, activated through a local Cisco IOS license file. LL-3750E-IPS= provides the IP Services relicensing option for used equipment, while 3750E-IPSLCB-QTY upgrades a 24-port IP Base configuration. Confirm the installed feature set and software entitlement rather than relying solely on the chassis part number.
WS-C3750E-24TD-E replaces WS-C3750G-16TD-E and is an additional migration option for WS-C3750G-24TS-E. Those predecessors reached end of sale on October 15, 2007, and March 16, 2009, respectively. The 16-port predecessor changes to 24 access ports, so the migration is not an identical port-density substitution.
Catalyst 3750-E StackWise Plus stacks nine members and provides 64 Gbps stack-ring throughput. CAB-STACK-50CM=, CAB-STACK-1M= and CAB-STACK-3M= are the standard cable options. The series supports mixed stacks with Catalyst 3750 switches, but member compatibility and software selection still need review before extending an existing stack.
Catalyst 3750-E uses X2-based 10 Gigabit Ethernet uplink interfaces, with X2-10GB-SR= and X2-10GB-LR= among the supported optical options. CVR-X2-SFP converts an X2 interface into two Gigabit SFP ports. Match the selected optic or converter to the remote equipment and fiber requirements when preparing the accessory order.
Yes, WS-C3750E-24TD-E supports OSPF, EIGRP, BGPv4 and IS-ISv4 with IP Services, plus OSPFv3 and EIGRPv6 for IPv6. The routing SDM template supports 11000 total unicast routes. That total includes connected hosts and indirect routes; template selection changes the allocation available for routing and other hardware resources.
No, WS-C3750E-24TD-E has one internal power-supply slot and includes C3K-PWR-265WAC. Backup power can come from external PWR2300-AC-RPS-N1= rather than a second internal supply. The internal AC input supports 100-240V AC, so redundancy requires an external power-system selection instead of ordering another internal power module.
WS-C3750E-24TD-E has data-only access ports, while WS-C3750E-24PD-E adds PoE with a 420W endpoint-power budget. Both configurations include IP Services and are discontinued. The TD configuration fits legacy installations with separately powered endpoints; the PD configuration addresses legacy installations where the switch supplies endpoint power.
WS-C3750E-24TD-E includes IP Services, while WS-C3750E-24TD-S includes IP Base. IP Services adds advanced dynamic unicast and multicast routing beyond IP Base's static and RIP routing capabilities. Both models are discontinued; the E configuration fits legacy dynamic-routing requirements, while the S configuration fits simpler legacy routing configurations.
WS-C3750E-24TD-E has passed its last support date, while C9300-24T-A is the current migration endpoint. The replacement chain passes through discontinued WS-C3750X-24T-E and discontinued WS-C3850-24T-E. The 3750-E configuration serves existing legacy environments; C9300-24T-A is the replacement choice for purchases requiring a current product rather than a discontinued spare.
